Three years ago, 4750 participants jointly played at ukulele festival in Papeete to make it into Guinness Book of Records.
Being dethroned by 8000 players in Hong Kong, Tahiti now wants to bring together 10,000 ukulele players on 24 February.
The song Te ra mai te tiare has been chosen for the challenge, with Tahiti Nui TV broadcasting a tutorial to help with practice.
The event is being organised by a range of institutions.
